| Basis for focus area |
Two MRDS records for black sands on Arkansas River (alluvial deposits); other on White River close to Black River-White River confluence named Jackson (Jackson-Independence) on the map. Titanium minerals also are a byproduct from frack sands. These are modern alluvial deposits with a carbonate rock source. |
| Identified resources |
Historical production of titanium (ilmenite). |
| Production |
During 1939 and 1940, 12.8 st of ilmenite were recovered by processing of sand from the Arkansas River by a company in Yell County. |
| Status |
Past mining; no current mining. |
| Estimated resources |
Unknown. |
| Geologic maps |
Haley and others (1993), scale 1:500,000. |
| Geophysical data |
Inadequate aeromagnetic and aeroradiometric coverage. |
| Favorable rocks and structures |
Sands in the Arkansas River. |
| Deposits |
Unnamed. |
| Evidence from mineral occurrences |
MRDS. |
| Geochemical evidence |
Full analyses by Dupont (company data). |
| Geophysical evidence |
None. |
| Comments |
Titanium and heavy mineral sands from the Arkansas River; mining frack sands, heavy minerals as byproducts. In 1949, 12 t sands extracted from the Arkansas River. Ongoing extraction of sand from the river to keep the river open presents the potential for production. |
| Cover thickness and description |
At the surface. |
